You guys are mostly missing the point, the library computers get cheaper prices than even a freshly installed no fingerprint computer because lots of poor people use them.

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.

Clear your cookies people
You're missing the point, library computers are used by a lot of poor people so those computers have cookies and other fingerprinting that makes companies think the users of those machines can't afford normal prices so they get even lower prices than if you had completely cleared your chace cookies fresh device and all that.
That doesn’t help anymore. These days they use device identifiers and IP addresses and all kinds of stuff like that to see if you’re the same person or not. I would imagine that in this case going to your own laptop or desktop would result in the same prices.
If you really want to hide try a browser like the Mullvad browser that specifically resizes and changes things used for fingerprinting.
Device finger printing should be illegal.
It's useful to stop ban evasion, but using it for personalised ads or prices should definitely be illegal.
Our government is run by sleeping 90 year olds. We should have a lot of laws right now that aren't on the books.
Musk is suing right now to make sure they don't make his illegal porn program illegal.
Well, also use privacy badger

Pretty sure that’s illegal where I live.
Only if those wankers get caught and convicted. Until then, it's just hearsay.
This is why I have a botnet of poor people's computers
It's not the library, it's the cache you never clear. She could have done this just as easily at home on a browser with a private window she hadn't signed into.
With the same IP, CPU, GPU, and networkcard??
Easily fingerprintable
Easily obfuscated, but also just clearing cache or using private browsing will more likely than not work.
I tried using waterfox and librewolf i think.
Every click on a new site was 5 capchas, its horrendously unusable, since probably they assume that all obfuscated user agent and other data are bots
I tried LibreWolf. It was such a bad experience.
It's a shame that the Internet is so bad that the browser has to go to such extreme lengths to give you any privacy that it makes the experience awful.

Unless you're running a virtual GPU (and changing it often enough to remain anonymous), tracking pixels are pretty difficult to obfuscate (the exact thermal environment your PC is in will even effect timing).
And thanks to big tech this state of the art tracking is on essentially every website.
Clearing site data/private mode is a way to ask nicely that websites don't track you, but user intention hasn't been respected for around 3 decades by now.

It's also using an iPhone instead of a desktop PC. Retailers think all iPhone users are rich (or at least less price-sensitive).
Cache != Cookies
This is not true in general. Some sites could charge you more based on your fingerprinting, but very few do as it’s easily proven and would cause massive backlash.
Amazon does for sure.
Definitely doesn’t. Easily testable and provable.
You're right. It is testable and provable, which is how I know they do lol
Proof please :)
Strange when there are entire sites set up for people to post Amazon deals, and not once in the 10+ years they’ve all been going has this ever happened when people followed the deal through.
Not sure what to tell you. It literally happened to me yesterday.
Cool, should be simple to get that proof then :)
Im sure it will be easy for them to go back in time and grab screen caps for you
They said it’s easily provable. That means they can easily provide proof 🤡
They’re saying it happens every time because of their digital fingerprint.
Clear your cookies and use a VPN. (And your browser probably has a setting you can enable to clear your cookies automatically every time you close out.)

Is it possible to instruct the browser, via extensions or something, to simply withhold that kind of information? I know websites need to render the page differently for different browsers and OS, but when it comes to things involving payment I'd rather deal with the browser quirks than get ripped off.
Yes, but then that itself becomes a signal.
You have to not only resist fingerprinting, but do it in the same way as other people who resist fingerprinting.
Or not resist at all, but provide fake, but realistic data with each request
It also marks you as extremely tech savvy, meaning you likely have large disposable incoming.
Only possible if you go to greater measures than just an extension.

Use tor browser or librewolf with a vpn that isnt owned by Kape. Check to make sure all cookies are deleted each session. Make each purchase with a new account. Ideally using an email alias otherwise it gets cumbersome fast. Personally I also use a one time virtual debit card.

All the more reason to use a VPN.
If I were a company looking to optimize profit by pricing goods at whatever limit the targeted consumer demographic would be willing to pay for, I would use a VPN as a signal to raise the price.
It doesn't matter who that consumer is behind the VPN. The VPN itself is a monthly subscription, and that indicates he/she has at enough disposable income to afford non-essential services.
To that point the library computer is free. I don’t know anything about VPNs or how to use them and I definitely shouldn’t have to pay for something for basic privacy. Library users improve the demand for libraries. Using a library computer is a win in basically all ways that really matter.
